Sintra is an all-in-one AI platform that gives you a team of specialized AI Helpers - each with their own name, role, and skill set - to handle the work that keeps your business running.

At the center of everything is Brain AI, a shared knowledge hub that learns your brand voice, stores your documents, and keeps every helper aligned with your business. Over 50,000 active users in 100+ countries rely on Sintra - and because helpers automatically collaborate and hand off tasks to one another, it works less like a tool and more like an actual team.

Sintra is for anyone who wants to:

We built Sintra with solo founders, small business owners, agencies, freelancers, e-commerce operators, and growing teams in mind. That said, anyone working on a business or project can benefit. Our users regularly report saving 5-60+ hours per week.

Each feature has its own detailed guide in the Help Center - here’s the overview.

Brain AI is the central knowledge hub that stores and organizes everything your

helpers need - your documents and files, structured databases (a lightweight built-in CRM), your Brand Kit, durable memory about your business, and searchable past conversations.

It learns about your business over time, so every helper delivers consistent, on-brand results without you repeating yourself. You can create folders, organize knowledge, and search across everything right in chat. Learn about Brain AI.

Sintra comes with 12 core AI helpers, each designed for a specific area of business.

For complex tasks, helpers call on each other automatically - dividing work by specialism, just like a real team would. Beyond the core 12, you can build custom helpers from scratch, hire marketplace helpers built by the community, and attach reusable skills to extend what any helper can do. ​Learn about Sintra's Helpers.

Team Chat brings all your helpers into a single conversation, coordinated by a Team Leader that plans the work, delegates each part to the right specialist, and pulls the results together for you.

It’s on by default in every new chat - just start typing to put the whole team on your request, or pick a specific helper if you’d rather work one-on-one. Team Chat is available on workspace plans and is currently in beta.

The Sintra Marketplace is a catalog of specialized helpers built by the community.

Browse and hire them instantly, customize any hired helper with your own rules,

or build and publish your own - and earn revenue share when other users hire

them.

Automations are standalone workflows that run in the background, outside of chat. They rely on integrations and trigger on a schedule or an event - like a new email arriving or a set time of day. Examples include the Social Media Manager, Inbox Manager, Meeting Notetaker, Daily Summarizer, and Facebook Commenter.

Learn about available automations.

Schedule work to run on a set timetable - a daily morning briefing, a weekly sales

report, or an hourly inbox check - with no need to repeat your instructions. You

can also set one-off reminders (e.g., "remind me Friday at 3pm to follow up with

the client"). Recurring tasks can run as often as every 10 minutes.

Once you define what you want done and how often it should happen, the Helpers execute those prompt-based tasks automatically in the background, freeing you up for more strategic work. You manage these tasks from the Tasks tab in the sidebar on the left side of the screen (they aren’t triggered directly from chat). Learn about Recurring Helper tasks.

Build and publish websites directly in chat. Describe what you want - or ask for changes to an existing page - and Sintra creates it with a live preview, no coding required. Publish to a Sintra subdomain or connect your own custom domain.

Sintra connects with 960+ apps and services, so your Helpers can work directly with the tools you already use - Shopify, Stripe, QuickBooks, Gmail, Google Calendar, Google Drive, Slack, Notion, Linear, GitHub, LinkedIn, Instagram, Facebook, YouTube, TikTok, and many more.

All your conversations are saved and searchable. Brain AI maintains context across sessions, so helpers remember what you’ve discussed and you can resume any thread without losing context.
